APPARATUS FOR HEATING WATER.

SPECIFICATION forming part of Letters Patent No. 534,494,'dated February19, 1895.

Application filed Ma 10, 18 94. Serial No. 510,690. (No model?) To allwhom it may concern.-

Be it known that I, JOHN S. COE, a citizen of the United States;residingat Paterson,in the county of Passaic and State of New J ersey, haveinvented certain new and useful Improvementsin Apparatus for'He'atingWater,

of which the following is a specification.

The object of my invention is to provide a heater for the economical andrapid heating of water for use in hotels or other buildings and for alldomestic purposes, and to provide an apparatus which may be used eithersep arate from and independent oforin conjunction with a range having aWater heating back or coil and whether the boiler is vertical orhorizontal.

The invention consists in having the water supplied by a pipe connectedwith the ordinary boiler or tank now in common use and having it pass toand from said boiler or tank through heating pipes, placed in an openheating chamber extending vertically a suit; able distance through thecentral portion of said tank or boiler, from the bottom thereof, saidcoils connecting with the main water space in said boiler'above thecrown sheet of heating chamber and at the bottom connecting with anannular water space, constructed as shown and hereinafter described, achimney or flue extending from the heating chamber through the upperportion of tank, and the placing of any number of gas or otherburnersunder said pipes beneath or in the bottom of said heatingchamber, so that when the gas or other inflammable substance is ig--nited the heating chamber and the pipes tional view of heatingapparatus on the line w m of Fig. 2. Fig. 2 is a plan view in section ofsame, on the line y y.

In the drawings A represents the tank or boiler; B, the water space inthe same; C, the vent pipe or chimney of heating chamber; D, the'heatingchamber or fire box; -E, space reserved beneath or in the lower portionof the fire box for burners; -F--, the pipes.

G-- is a water space formed by the flange G' and by-the cylindricalportion which s cast to the bottom G both the flangei G- and the bottomG being screwed "to and around the lower part of the fire box or heatingchamber -D-.

The coils are connected with or enter the annular water space'-G- at 4,4, 4, and are connected with the main water-space B above the crownsheet at 5, 5, 5.

I is a valve-fitting secured to the bottom of the tank and connectingwith the water spaces B and G as clearly. shown in Fig. 1. Thisvalve-fitting is provided with a faucet H and with a valve 1' fitted toa suitable seat in the valve-fitting and adapted to close communicationthrough the port 1 into the space B when the valve is in one position,and to close the communication with the faucet H and port 1 into thespace G whenin its other position. When the faucet H is closed by thevalve I and the valve K in the outlet pipe K is open the hot water isallowed to circulate through the building in the ordinary way asreadily. understood. 7

In the drawings J is the supply pipes which may be attached as shown inthe draw-.

ings' or connected with the tank in the usual way at the side of theboiler and -K- is the outlet pipe.

Under the coils -F- in the lower part E- of the fire box .'D are placedany suitable.

number of burners to supply the desired heat. It is not deemed necessaryto show in the drawings said burners as any burners that will accomplishthe purpose may be employed.

' The pipe J- is connected with the cold water and K- With thedistributing pipes for the purpose of carrying the hot water through thebuilding in the ordinary way in which case the faucet H is closed andthe circulating valve I- is open.

When the water is to be heated for immediate use in the room in whichthe boiler is situated, or in any other room in the building where acirculating valve is employed or placed then the pipe -K is not used butthe valve I- is used and the water is drawn at faucet --H by amanipulation of the circulation valve I, the closing of the valveopening the faucet and permitting the water to go from the coils andwater space G and the opening of the valve closing the faucet --I- As isobvious many styles of pipes or coils may be used and variousarrangements thereof may be adopted in rigging up the heating chamber orfire box without departing from my principle of having heating pipes inthe heating chamber connected with said two water spaces, and havingsaid water spaces connected by a two way valve, as shown.

I am aware that there are many and various ways and methods of heatingwater, and that (lifierent styles of pipes or coils have been used forthat purpose, and, therefore, I do not claim anything more than is shownin the drawings, namely, a water heater complete, being a new article ofmanufacture consisting of the novel construction, combination andarrangement of the boiler, heatingchamher and line, an annular waterspace around the bottom of the heating chamber, a set of coils, onewithin the other, connecting the water space in the boiler and theannular water space around the bottom of the heating chamber, the twoway valve, the feed and supply pipes.

It is obvious that when the range is not in operation my method will bemuch more rapid and economical than startinga range,

and in warm weather it will obviate the me cessity of having a rangegoing in order to have hot Water.

With the foregoing description of my invention, what I claim, and desireto secure by Letters Patent, is-

1. The combination with a tank or boiler,

of a heating chamber within the same, a

flanged cylindrical portion forming a water space around the lower partof the said heat ing chamber with communication between said chamber andthe lower portion of the boiler, the heating pipes arranged within thewithin the heating chamber, connected at the top with the main waterspace of the boiler above the crown sheet, an annular water space aroundthe lower end of the heating chamber with which the heating pipescommunicate, the valve-fitting connected with the lower portion of theboiler and provided with the circulating valve connecting the two waterspaces, and the supply and outlet pipes connected with the main waterspace of the boiler and with the annular water space around the lowerend of the heating chamber respectively, substantially as shown anddescribed.
